NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA02-018.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
THIS INVESTIGATION WAS OPENED ON CERTAIN FORD PICKUP TRUCKS AND VANS TO EVALUATE THE EFFECTS OF A VALVE STEM EJECTION (WITH RAPID AIR LOSS) AND A SLOW LEAKING VALVE STEM ON VEHICLE HANDING.DURING THE INVESTIGATION, ODI EVALUATED OVER 1,100 COMPLAINTS AND WARRANTY CLAIMS, CONDUCTED VEHICLE DYNAMIC TESTING ON A SUBJECT VEHICLE WITH THE FAILURE MODE REPLICATED, INTERVIEWED OWNERS, AND EXAMINED COMPLAINT VEHICLES IN THE FIELD.THE RESULTS OF THE TEST PROGRAM INDICATES THE EFFECT OF A VALVE STEM EJECTION ON THESE VEHICLES IS EASILY CONTROLLED. FURTHER, WITH A POPULATION OF ALMOST 900,000 VEHICLES, HAVING TWO TO FOUR YEARS OF EXPOSURE, ODI IS AWARE OF ONLY 3 MINOR CRASHES AND IS UNAWARE OF ANY INJURIES.THE SMALL NUMBER OF CRASHES RELATIVE TO THE LARGE POPULATION OF VEHICLES IS CONSISTENT WITH THE TESTING WHICH WAS PERFORMED. THEREFORE, THIS INVESTIGATION IS CLOSED.SEE THE ATTACHED REPORT FOR FULL TECHNICAL DETAILS.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Engineering Analysis EA02-018. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.
What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
